What is up with Katia Gordeeva's two daughters, Daria and Liza?

I haven't heard anything about Daria in a few years and she wasn't in the Family skating event last year. I searched for her on Twitter and found this, which worried me- sounds like she's doing lots of drugs and drinking:

I so want her to turn out happy and healthy. LOVED Sergei and Katia and have always had a tender spot in my heart for Daria.

And I heard that Liza is an upcoming skater? has anyone seen her skate recently? Is she considered a contender for national novice yet? With Ilia and Katia as her parents, she certainly has both great jumping and artistry genes.

Thanks in advance for any info you can provide on either of the girls.
